The command,

find . -name "*.back" -type f -exec rm -f {} \;

worked well and cleared out about 50GB or older incremental versions. I ran this while I was out for a while and I didn't run it under time, so I can't comment on how fast the method is compared to other possibilities. I generally presume that there is no fast script based method to process a directory tree with 4+ million files.

I also did a defrag/optimize (auslogics) and clean out of MFT records. All told it took almost 24 hours to run, but I find I need to keep these backups well maintained, or they eventually bork and you have to reformat and start again. It seems as if rsync tends to lead to very fragmented repositories. I have never quite understood why you get lots of fragmenting on a drive with 500GB of empty space.

Thanks for all the additional explanations. I do always try to understand what a script is doing and why you would choose one method over another. I think I need to read a bit about exec.
